Hi,
I'm running sagemath 9.0 in Ubuntu 20.04 with jupyterhub and jupyterlab. When I try to display a simple ·D graphic like
p1 = sphere(color='red', opacity=.5)
show(p1,axes=True,viewer='threejs')
nothing is displayed.
In the console, I get the message
/hub/nbextensions/threejs/examples/js/controls/OrbitControls.js
/hub/nbextensions/threejs/build/three.min.js
not found.
Does anybody know how to solve the problem?
Thanks in advance.
